Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
i made this project to try to create RSC service on arduino
developer.bluetooth.org/.../runningspeedandcadence.zip
unfortunately the server starts but i'm not able to...
Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
Hi there! I am a beginner of bluetooth technology.
We try to build a kind of IoT based on bluetooth mesh nodes with nRF51822. According to the instruction of nRF Connect...
I've found out that softdevice S130 cannot handle the length longer than default MTU(23).
But I know L2CAP is responsible for assembling and disassembling packet.
So...
I'm using nrf51822 & S130 to read the temperature humidity values every 5 seconds from AM2301 sensor. For that I am using timer in system on sleep mode. The current consumption...
Thanks for all support so far.
One thing I want to ask that does your nordic Beacon chip can support Bluetooth 2,0 as well ?
I mean is it backward compatible
hello,
I'm using nrf51822 as proprietary model, I found it can not received 500 pkts complete from 500 nrf24lE1 labels during 2 seconds(every nrf24le1 send one pkt per...
I am trying to develop a BT Microphone that can pair directly with a BT speaker.
The Mic will act as a server for the speaker (client).
I have some nRF52 EVB.
Do...
We have used a logic analyser to verify this.
SPI initialised and talks nicely with an ADXL362 accelerometer part.
We have interrupts configured.
We go into sd_power_system_off...
Hello! I've soldered my first board with nrf52832 chip + PA on it. Everything works well beside the radio. The real distance (less 10m) even worse than on nrf52dk despite...
Just got my nrf52DK and connecting and dropping the HRM demo to it worked like a charm but since then, all attempts to get something else to run failed. Erasing all and reprogramming...
I have a very simple test program to run the radio through the transmit sequence, each task is called from the radio interrupt handler according to each event.
The process...
I'm pretty new with microcontrollers and SPI.
I connected fisically an nrf51822 microcontroller to an external SPI flash memory.
I connected MISO MOSI ports to some random...
I am using SDK 12.0.0.
I am working with low_power_pwm_init() to initialise the pwm and I have passed a handler while initialising. I want to stop the pwm from the handler...
